I imagine because China has spent more time on the required infrastructure to make this happen. Spain is trying to stop something that is set to happen on Oct 1, so they have a finite amount of time to suppress the information.
By the same token, they're also not the home of a bunch of friendly companies that will implement the work, unlike China, and they don't have a long history of trying to stop the flow of information, unlike China, and they don't have a effectively infinite budget, unlike China.
I'm betting against Spain on this one. Go Catalonia!
